摘要
随着“十二五”规划(2011-2015)的实施及西部经济的发展,西部的交通建设也
达到一个新的高潮,大量的公路隧道也随之出现。为研究软弱围岩公路隧道的变形规律,
本文依托连霍国道主干线(GZ45)永登—古浪段高速公路乌鞘岭隧道为依托,结合隧址
区的工程地质条件,在施工过程中埋设压力盒、锚杆钢筋计、混凝土应变计、拱顶下沉
量测测点、周边位移量测测点,对软弱围岩公路隧道的荷载作用特性和变形规律进行长
期跟踪监测,同时应用大型通用有限元分析软件(MIDAS-GTS),对软弱围岩公路隧道的
施工过程进行有限元数值仿真模拟。
结合现场量测结果,以及有限元分析软件计算结果,总结隧道的荷载作用特性与变
形规律,为施工提供一定的科学依据和指导,确保了施工的安全。
本文的研究成果的应用为乌鞘岭隧道工程的建设提供了理论依据,同时也可为后续
的类似工程地质条件下隧道修建提供设计和施工经验,因此具有较好的参考价值。

With the "12th Five-Year Plan (2011-2015) implementing and development of the
western economy, transportation construction in the west also reached a new climax, a lot of
road tunnel appears. In order to study the deformation rule of weak rock road tunnel, in this
article rely on Lianhuo national trunk road (GZ45) Yongdeng - Gulang segment the highway
Wushaoling tunnel as the basis, combined with the engineering geological conditions of the
tunnel site, laying in the construction processpressure cell, bolt reinforced dollars, concrete
strain gauge measuring point, the crown settlement, peripheral displacement point to
long-term tracking and monitoring, load characteristics and deformation laws for weak rock
road tunnel, while applications for large general-purpose finite elementanalysis software
(MIDAS-GTS), finite element numerical simulation of the construction process of the weak
rock road tunnel.
Combine the results of field measurements and finite element analysis software to
calculate the results, sum
